No, separate 8x3x3/4-1 stones. I will try to upload some photos later on the "show off your arks" thread.
Wow, that is really odd.Just weighed the two stones.
Soft ark: 7 3/4x3x1 = 851 grams
Hard ark: 8x3x1 = 791 grams.
Good to know. I was just looking for something the other day...Great thread. Hope I am not taking things off topic.
I learned a great trick for testing scales. The US mint requires accuracy beyond most needs, so any nickel from pocket change that isnt beat up weighs exactly 5.00 grams. With most larger stones above several hundred grams in weight you can extrapolate pretty decent accuracy.
